Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
In the embodiment, the original structure is taken as the cable trench 5 as an example, and a new municipal facility is newly installed below the cable trench 5, so that a foundation pit needs to be excavated below the original cable trench 5, and in order to prevent the collapse of the original cable trench 5 and the soil layer below the original cable trench 5 in the construction process, the internal-bracing external-support reinforcing structure is provided.
Build fixed groined type support frame 1 in cable pit 5, groined type support frame 1 includes that crossbearer pipe A2, crossbearer pipe B3 and erects a pipe 4 fixed together through right angle fastener, and wherein crossbearer pipe A2 and erects 4 both ends of a pipe and all fix on the inner wall of cable pit 5, and crossbearer pipe B3 sets up along the longitudinal direction of cable pit 5. In order to ensure that the two ends of the horizontal frame pipe A2 and the vertical frame pipe 4 are connected and fastened with the inner wall of the cable trench 5, preferably, the two ends of the horizontal frame pipe A2 and the two ends of the vertical frame pipe 4 are both provided with adjustable drag supports, the adjustable drag supports are common devices for construction sites, and the structure and the principle are not repeated herein.
The top of the foundation ditch below the cable trench 5 is provided with a steel plate 6, and the steel plate 6 corresponds to the middle position of the # -shaped support frame 1. The symmetry be equipped with a plurality of round hole on steel sheet 6, four round holes have been established to this embodiment, and original structure bottom is equipped with four holes that correspond with the round hole, and every has all worn two reinforcing bars 7 between to the round hole and the hole that correspond, and the lower extreme welding of reinforcing bar 7 is on steel sheet 6, and reinforcing bar 7 upper portion upwards welds in proper order on crossbearer pipe A2 and the crossbearer pipe B3 of below. In order to ensure firm welding and increase the welding area, the upper ends of the reinforcing steel bars 7 can be welded on the transverse frame pipe B3 after being bent. Similarly, the lower part of the steel bar 7 penetrating through the round hole can be bent and welded at the bottom of the steel plate 6, so that the welding area is increased, and the welding is firmer.
During construction, a fixed # -shaped support frame 1 is erected in the cable trench 5, four holes are drilled at the bottom of the cable trench 5 through electric drills, and the four holes penetrate through a soil layer below and are communicated with the top of a foundation pit below. Install steel sheet 6 at the foundation ditch top of below, four round holes on the steel sheet 6 correspond well with the hole, then pass reinforcing bar 7 between round hole and the hole that corresponds, weld 7 both ends of reinforcing bar on steel sheet 6 and well style of calligraphy support frame 1 respectively, support and the 6 bearings of bottom steel sheet through inside well style of calligraphy support frame 1 to cable pit 5 like this, form double reinforcement degree, the overall stability of cable pit 5 has been ensured, prevent the local collapse of the soil horizon below the cable pit 5 simultaneously, the safety of workman when having guaranteed the construction in the foundation ditch.
Finally, it should be noted that: the above examples are only intended to illustrate the technical solution of the present invention, but not to limit it; those of ordinary skill in the art will understand that: the technical solutions described in the above embodiments may still be modified, or some technical features may be equivalently replaced; and such modifications or substitutions do not depart from the spirit and scope of the corresponding technical solutions of the embodiments of the present invention.
